1 Claim.

This invention relates to wrecking bars and it consists in theconstructions, arrangements and combinations herein described andclaimed.

It is the cardinal object of the invention to provide a wrecking barhaving clamp means whereby the bar may be. secured to rungs of a ladderfor supporting the ladder in proper and secure position when in use.

It is also an object of the invention to provide clamp means which areadjustable longitudinally of the wrecking bar so as to accommodate rungsof various constructions of ladders, where spacing of the rungs may notbe uniform.

Additional objects, advantages and features of invention will beapparent from the following description and accompanying drawing,wherein Figure l is a front elevation of a ladder having my constructionof wrecking bar attached thereto.

Figure 2 is a vertical section through the ladder showing my device inuse.

Figure 3 is a fragmentary enlarged sectional view through the wreckingbar illustrating the mounting of the clamp means.

Figure 4 is a front elevation thereof.

Figure 5 is a fragmentary elevation, illustrating a further andimportant use of the invention.

There is illustrated a conventional wrecking bar ill embodying a hookportion ll terminating in a claw l2 as is customary. Upon the shankportion 53 at the base of the hook H a flattened portion i4 is formed,suitable for driving nails, spikes and the like. A claw member l5completes the bar structure.

Intermediate the length of the shank IS a pair of slots iii are formed,extending longitudinally of the shank for receiving fastening devices,now to be described.

A clamp device ll is employed with each slot I6. and in the presentinstance is formed from a metal plate of suitable gauge bent at one endin the form of a semi-circular loop l8 of a diameter to admit a rung ofa ladder l0 by way of the open side of the loop. The other end of theplat-r: is extended as a flat portion l9, apertured as at it forreception of a bolt 2!, which is headed at 22, and threaded upon theopposite end for receiving a wing nut 23.

In mounting the clamp devices to the wrecking bar, the flat portions l9are laid fiat upon the bar, the apertures 25] being alined withrespective slots l5. A bolt 2! is next inserted through apertures andslots and a wing nut 23 is engaged upon the threaded end thereof to holdthe clamp devices upon the bar. Obviously, the loop portion I8 may be sodisposed as to be suspended from a rung of the ladder, as in Figures 1and 2, or the loop portions may be reversed as in Figures 3 and 4. Itwill be apparent that the wrecking bar may be employed as such while theclamps are attached, or if desired, the clamps may be quickly removed.

The particular use to which the device may be employed is to secure aladder at its upper end, from a building, such as in Fig. 2, or over theridge of a roof as shown in Fig, 5, disposing the hook portion ll over aguttering. In applying the wrecking bar to a ladder, the clamp devices Hare loosened to such extent as to admit a rung of the ladder withinrespective loops IS. The wing nuts 23 are then screwed home so as todraw the flat portions l9 snug against the shank I3 when the rungs willbe firmly gripped. The wrecking bar thus becomes a rigid part of theladder, which may be manipulated in a manner to cause the hook to engagea suitable rigid member for support of the ladder.

It may happen that the rungs of various ladder constructions will varyas to the distances of spacing but this may be accommodated by reason ofthe elongated slots l6, permitting the clamps to be moved longitudinallyof the bar.

While I have specifically shown and described a preferred construction,this is by way of illustration only, and I consider as my own all suchmodifications in constructions as fairly fall within the scope of theappended claim.

I claim:

A new article of manufacture consisting of a wrecking bar having a hookend and a shank portion of substantial diameter terminating in a clawportion having a curvature reverse to that of the hooked end, the shankbeing of a length to extend beyond a plurality of rungs of a ladder andpresenting the curved portion of the claw portion against the lowermostrung, said shank having a pair of slots extending longitudinally thereofand spaced inwardly of the claw portion, a clamp member cooperable witheach slot, each clamp comprising a fiat portion having an aperturealigned with a respective slot and a loop portion adapted to partlyencircle a rung of a ladder, a bolt extended through the alignedaperture and slot, and a nut on the bolt for drawing the flat portionand the loop in the direction of the shank and maintaining the clawportion firmly against the said rung of the ladder.

NELS C. SORENSON.
